DDS238-4 RS48 series single-phase full electronic watt-hour meter using a dedicated large-scale integrated circuits, with anti-theft, high accuracy, high overload, low power consumption, light weight and so on. It can measure single-phase AC active energy with reference frequency of 50Hz or 60Hz. Meter for fixed installation indoors, the use of ambient temperature is -40 ℃ ~ +70 ℃, the relative temperature does not exceed 80%. This product complies with GB / T17215.321-2008 «Particular requirements for ac measuring equipment - Part 21: Static watthour meters (Class 1 and Class 2») - All technical requirements for single-phase watt-hour meters.
With pulse counter.
With pulse signal output terminal, the user can access according to need.
The ammeter can continuously flash when the load current is 0.4% (level 1) or 0.5% (level 2) under the condition of reference voltage, reference frequency and power factor of 1.
Meter with anti-submarine logic circuit, when the current circuit is no current, 115% of the reference voltage is applied, the start-up current to produce a pulse of ten times the time measured when the output does not produce more than one pulse.
Installation and use
Meter
should be installed indoors, the installation of the meter should be
fixed on the floor mounted on a solid fire-resistant walls, the proposed
installation height of about 1.8 meters.
Meter should be in accordance with the junction box on the wiring diagram wiring, with copper or copper connector.
Measures should be taken when using the energy meter where there is a lot of thunderstorms.
Power meter LCD liquid crystal displays the total active power.
